我还没有找到问题的解决方案,但是几天前有人已经问过同样的问题了 - (Rails Server Keeps Exiting(SocketError))

启动rails服务器后,系统返回一些我无法理解的错误.要在我的Mac上安装Ruby on Rails,我做了http://railsapps.github.io/installrubyonrails-mac.html上列出的所有内容.

这是我的终端回复:

$ rails server

=> Rails 4.2.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
